Embodiment 1

[0028] A kind of method that utilizes cherry wood sawdust to prepare wood-plastic composite material, comprises the following steps:

[0029] S1. Sawdust treatment

[0030] Add 60 parts of cherry wood chips, 6 parts of calcium stearate and 4 parts of nano-alumina into the ball mill, and stir for 20 minutes to obtain modified wood chips.

[0031] S2. Mixing

[0032] Add 5 parts of modified basalt fiber, 6 parts of glass fiber, 30 parts of waste plastics, 3 parts of nano-zinc oxide and 3 parts of magnesium salt whisker into the modified wood chips, and mix uniformly to obtain a mixture.

[0033] The modified basalt fiber is obtained by immersing or coating the basalt fiber with a modifier, and the modifier includes: 40% film-forming agent, 10% coupling agent, 3% lubricant, 8% Modified nano-SiO 2 particles and the rest is water.

[0034] S3. Granulation

[0035] Add 0.5 part of heat stabilizer, 0.5 part of lubricant and 0.5 part of solubilizer to the mixture, continue stirri...

Embodiment 2

[0040] A method for preparing wood-plastic composite materials using cherry wood chips, wherein step S2. In mixing materials, 10 parts of modified basalt fibers, 6 parts of glass fibers, 30 parts of waste plastics, and nanometer zinc oxide are added to the modified wood chips. 3 parts and 3 parts of magnesium salt whiskers, mix evenly to obtain a mixture. Other steps are with embodiment 1.

Embodiment 3

[0042] A method for preparing a wood-plastic composite material using cherry wood chips, wherein step S2. In mixing materials, 15 parts of modified basalt fibers, 6 parts of glass fibers, 30 parts of waste plastics, and nanometer zinc oxide are added to the modified wood chips. 3 parts and 3 parts of magnesium salt whiskers, mix evenly to obtain a mixture. Other steps are with embodiment 1.

Abstract

The present invention provides a method of preparing a wood-plastic composite material from cherry wood chips, and the method comprises the steps of wood chip treatment, mixing, granulation, and forming. According to the method, the wood chips are firstly modified with calcium stearate and nano-alumina, and then mixed with modified basalt fiber, glass fiber, waste plastic, nano zinc oxide and magnesium salt whisker for granulation and forming. The prepared wood-plastic composite material uses the cherry wood chips and the waste plastic as main materials, is beneficial to the reuse of waste andscrap, can save energy and relieve environmental pressure, and has better mechanical properties.

Description

technical field [0001] The invention relates to the technical field of wood recycling, in particular to a method for preparing wood-plastic composite materials from cherry wood chips. Background technique [0002] Sawdust is the tailings or waste after wood processing. In the past, most of them were used as fuel by farmers. With the emergence of new energy sources, the fuel function of wood chips has been greatly weakened. The waste sawdust produced by industrialization occupies a large amount of land, pollutes the environment, and seriously It even affects the production and operation of processing enterprises. Cherry wood is a commonly used furniture material, and a large amount of scraps and scraps are produced every year. If they are discarded randomly, it will not only pollute the environment, but also cause great waste. [0003] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to th...
